Black Panther, Wakandan King + Animation Module + Phyrexian Altar

Black Panther, Wakandan King

Animation Module

Phyrexian Altar

How it works

1. Cast Black Panther either from your hand or from the command zone by paying plus commander tax, if applicable.
2. When Black Panther enters the battlefield, it triggers, putting a +1/+1 counter on a land you control.
3. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
4. When the Servo enters the battlefield, Black Panther triggers.
5. Holding priority, activate Phyrexian Altar by sacrificing the Servo, adding 1.
6. Resolve the Black Panther trigger, putting a +1/+1 counter on a land you control.
7. Repeat from step 3.

This clever loop starts with Black Panther, Wakandan King entering the battlefield, which immediately triggers its *Survey the Realm* ability to seed a land with a +1/+1 counter. That counter placement wakes up Animation Module, allowing you to pay the required mana to spawn a 1/1 Servo artifact creature token. When that Servo arrives, it triggers Black Panther, Wakandan King all over again, feeding a loop that is entirely sustained by sacrificing the Servo to Phyrexian Altar to generate the exact mana needed to pay Animation Module's trigger fee.
